I accidently changed the permission for my hard drive on Windows 7. I have C:\ and D:\ but after I altered the permisson of my D:\, now the access is denied.
In the drive Properties under the Security tab, I ticked all the Deny boxes of the permission settings.
I think the administrator was denied too. Now when I check the drive Properties, there is no Security tab. How can I change back the permission as all my documents are in it. Access are denied completely and I need help. Please!
